Forwarding all mail to your ISP’s smtp server with postfix and CentOS 5.4

I needed to forward all server mails to external email addresses and I had to use my ISP's smtp to do it. This is because everything is blocked by my ISP to combat spammers just making their own smtp server at home and then running it all hours of the day. To do this, you should have postfix installed and running already.
